In the Elements Tab of Chrome Dev Tools I can't right click any DOM Node anymore. I'm talking about the following menu that right click usually opens:

Furtheremore usually if you hover over DOM Nodes in the Elements Tab, the actual element on the website will be highlighted. This also doesnt work anymore. I have to explicitly left click the DOM Node and only then the element on the website will be highlighted. Before that it would work even just on hover.

I tried restarting my Browser and resetting Preferences of Dev Tools to default. Nothing works.
